Brief summary

This trial studies the side effects of pembrolizumab with or without chemotherapy in treating patients with stage IV non-small cell lung cancer that has come back (recurrent) and has spread to other places in the body (advanced). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as pemetrexed and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab with or without chemotherapy may shrink the tumor in older patients with non-small cell lung cancer.

Detailed description

The primary and secondary objectives of the study: PRIMARY OBJECTIVE: I. To estimate the adverse event profile of MK-3475 (pembrolizumab) in non-small cell lung cancer patients who are age 70 years of age or older and who are treated with MK-3475 (pembrolizumab) +/- chemotherapy in a first-line setting. SECONDARY OBJECTIVES: I. To estimate overall survival. II. To describe patient quality of life during the treatment using the Linear Analogue Self-Assessment (LASA) questionnaire. III. To explore whether Comprehensive Geriatric Assessment (CGA) -derived risk score is able to predict rates of severe adverse events in older cancer patients who receive MK-3475 (pembrolizumab) or MK-3475 (pembrolizumab) + chemotherapy. OUTLINE: Patients are assigned to 1 of 2 groups. GROUP A: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. GROUP B: Patients receive pembrolizumab IV over 30 minutes, pemetrexed IV over 10 minutes, and carboplatin IV per institutional guidelines on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up annually for up to 5 years after registration.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of Grade 3 or Worse Adverse Events Post RegistrationUp to 7 days of last day of treatment, up to 6 monthsAssessed by National Cancer Institute Common Terminology Criteria in Adverse Events version 5.0. The proportion of patients experience grade 3 or worse adverse events (AEs) will be summarized by frequency and percentage along with a 95% confidence interval (CI) separately by type of therapy (monotherapy or combination therapy) as well as combining the two cohorts. All other individual AEs will be analyzed in an exploratory and hypothesis generating manner; including and not limited to multi-variate logistic regression models considering the baseline demographics and the presence/absence of the AE.

Secondary

MeasureTime frameDescription
Overall Survival (OS)From study registration to death or the last follow-up whichever occurs first, assessed up to 3 yearsWill be summarized using the Kaplan-Meier estimator, separately by monotherapy or combination therapy as well as by the combined cohort.
Quality of Life (QOL): Linear Analogue Self-Assessment [LASA] QuestionnaireUp to 9 weeksThe overall quality of life score (the first question of the Linear Analogue Self-Assessment \[LASA\] questionnaire) at each time point as well as change from baseline will be summarized by mean (standard deviation), median (range) along with a longitudinal plot. The median quality of life (QOL) change from baseline along with a 95% confidence interval (CI) will be estimated using the Hodges-Lehmann method. The overall quality of life score will be measured on a scale from 0-10, with higher being better.
Comprehensive Geriatric Assessment Risk ScoreAt baseline. Per the protocol section 13.5,Comprehensive geriatric assessment would be examined combined by arm.The geriatric risk score, measured as low, medium, or high, will be summarized in a 3X2 frequency table with adverse events.
